Xerox ColorQube 8570 / 8870 Error 91,720.00:XX

I am working with Xerox Solid Ink Printers since like 2001 Year from now, I started with the Panzer-Build Xerox Phaser 860

and now I own two 8870 units for daily basis printing.

My most recent addition, 8870 infact, I had set up, upgraded RAM to 2x 1024MB and change the language to German and various setting. The unit is just printed 30 Pages and all but one of these pages where status, ink nozzle check and configuration pages.

Now yesterday I was printing some invoices for my tax accountant, the Printer was in "standby" mode due automatic idleing.

The print engine started to make its typical "wake" up noise and the fan started blowing and suddenly the screen went fully black and the machine restarted itself.

I was a little worried at this point. Machine booted itself just like a "cold" reboot with the cleaning procedure (which of curse waste a amount of ink due to purging) and at about 15% Warmup / Cleaning I was confronted with the Error message :

Error 91,720,00:30

30 stands for the pages printed

At this point the printed was ONLY filled with starter blocks that have the "small" shape of 8570 Blocks.

And the error itself 91,720 indicates a Print Head Tilt error but after some research I found various attempt to resolve this matter

"I suggest you look for ink spills or obstructions around the printhead, and try to remove as much as possibe, also reboot the printer."

I looked with a small flashlight, but since I never added any additional Ink there was obviously no obstruction at all.

I did Power it up two times to check if the error message sort it self out by itself, and I did wait 20~40 Min betwen power cycling but it still showed the error at about 15% warm up. Not even the blank cleaning sheet was pushed tru the printer as I am used to.

Hm.. I literaly used the machine for like 2 Hours and it gave me this bad look, Y U doing this colorqube?

Whatever, time to contact some one: I tried to ring my merchant, but I only got to hotline and in contact with an UserHelpDesk agent, she was friendly but this matter was clearly for 2nd Level and not her expertise.

She created a service ticket, but I was unhappy, maybe 2nd Level will get back to me in 48 Hours...

I couldn't wait and I called the TOLL FREE Service Hotline for german Customers

I stated the Serial No of my machine to the hotline "robot" and I was patched tru to an very ressourcefull Xerox Hotline Agent, I forgot her name, but she had an either polish or bulgarian german accent, (my guess hotline is outsourced somewhere there)

I told her exactly what happend and I told her I that am using Xerox Solid Ink printers since ages.

The printer, since I was just recently purchased, was not showing in the "system" yet. She told me I should connact my retailer for that matter, he could push the completion to register my printer. Before a completed registration the printer wouldn't be covered by its 1 year warranty. Okay, thats not good.

BUT she told me to try something:

Secret button combination to boot the printer into "service" Mode or something

Select Reset Error Log

Reboot the machine? Yes

She told me now to be patient and that she would call me up right again within an hour.

Wow, 1min action.

the printer then rebooted for like 45 min showing the Error again and again but it keept rebooting, since the Error Log will be deleted upon rebooting.

After a fresh cup of coffee and further 10min suddenly the printer was all good and printing the Test-pages and configuration pages.

Now yesterday after these simply "repair" steps I printed over 2.000 Pages for various customers and my tax accountant. Refilled all ink slots with one "Europe" Coded ink block (I live in germany duh) and its all fine

Re: Xerox ColorQube 8570 / 8870 Error 91,720.00:XX

ColorQube 8570 has stopped working. I've had it over two years so I assume it is out of warrantry. It started making load mechanical clicking noises (like machine gun fire) and cycling through start up. Printer Error:91,720,000:XXXXX shows up presiodically. I tried powering off but each time machine is stuck in noisy start-up cycle.

An earlier user stated:

Secret button combination to boot the printer into "service" Mode or something

Select Reset Error Log

Reboot the machine? Yes

She told me now to be patient and that she would call me up right again within an hour.

Wow, 1min action.

I guess this worked but I don't understand what the user actually did. Would it help to boot it into service mode and clear the error log, and if so, how would I do that? What is the secret button combination?
